SAFETY CONSIDERATIONS
Installation and servicing of air-conditioning equipment can
be hazardous due to system pressure and electrical components. Only trained and qualified service personnel should
install, rep air, or servic e air-conditionin g equipment.
Untrained personnel can perform basic maintenance functions of cleaning coils and filters and replacing filters. All
other operations sh o uld be perfor me d by trai ne d se rvi ce personnel. When working on air-conditioning equipment,
observe precautions in the literature, tags and labels
attached to the unit, and other safety precaution s that may
apply.
Follow all safety codes. Wear safety glasse s and work g love s.
Use quenching cloth for unbrazing operations. Have fire
extinguisher available for all brazing operations.
WARNING:
CAUTION: Ensure voltage listed on unit data
plate agrees with electrical supply provided for the
unit.
INSTALLATION
Unit is shipped in the vertical discharge configuration. To
convert to horizontal config uration, remove hor izontal duct
opening covers. Using the same screws, install covers on duct
openings in basepan of unit with the insulation-side down.
Seals around duct openings must be tight.
I. STEP 1 — PROVIDE UNIT SUPPORT
A. Roof Curb
Assemble and install access ory roof curb in accorda nce with
instructions shipped with curb. See Fig. 1. Install insulation,
cant strips, roofing felt, and counte r flashing as sho wn. Duct-
work must be attached to curb, not to the unit. If electric or
control power is to be routed through the basepan, attach the
accessory thru-the-bottom service connections to the
basepan and roof curb in accordance with the accessory
installation instructions. Connections must be installed
before unit is set on roof curb.
IMPORTANT: The gasketing of the unit to the roof curb is
critical for watertightness. Install gasket supplied with the
roof curb as shown in Fig. 1. Improperly applied gask et can
also result in air leaks and poor unit performance.
Curb should be level. This is necessar y for unit drain to function properly. Unit leveling tolerances are shown in Fig. 2.
Refer to Accessory Roof Curb Installation Instructions for
additional information as required.
B. Slab Mount (Horizontal Units Only)
Provide a level concrete slab that exte nds a m ini mum o f 6 i n .
beyond unit cabinet. Install a gravel apron in front of condenser coil air inlet to prevent grass and foliage from
obstructing airflow.
NOTE: Horizontal units may be installed on a roof curb if
required.
II. STEP 2 — FIELD FABRICATE DUCTWORK
Secure all ducts to ro of curb and b uil ding stru cture on v ertical discharge units. Do not connect ductwork to unit. For hor-
izontal applications, field-supplied flanges should be
attached to horizontal discharge open ings and all ductwork
should be attached to the flanges. Insulate and weatherproof
all external ductwork, joints, and roof openi ngs wi th co unter
flashing and mastic in accordance with applicable codes.
Ducts passing through a n unco nditi one d spa ce mu st be ins ulated and covered with a vapor barrier.

Fig. 2 — Unit Leveling Tolerances
If a plenum return is used on a vertical unit, the return
should be ducted through th e roof deck to comply with applicable fire codes.
A minimum clearanc e to comb ustible s is no t required around
ductwork on vertical discharge units. On horizontal discharge units with electric heat, a minimum clearance of
1.0 in. is required for the first 12 in. of ductwork. Cabinet
return-air static pressure should not exceed –0.35 in. wg
with Durablade econ omizer, –0.30 in. wg with EconoMi$er,
or –0.45 in. wg without economizer.
III. STEP 3 — INSTALL CONDENSATE DRAIN LINE AND
EXTERNAL TRAP
Condensate drain connections are located on the botto m and
side of the unit. Unit discharge connections do not determine
the use of drain connections; either drain connection can be
used with vertical or horizontal discharge units.
When using the standard side drain connection, make sure
the plug in the alternate bottom connection is tight before
installing the unit.
To use the bottom drain connection for a roof curb installation, relocate the factory-installed plug from the bottom connection to the side connection. See Fig. 3. The piping for the
condensate drain and external trap can be completed after
the unit is in place.
All units must have an external trap for condensate drainage. Install a trap at least 4 in. deep and protect against
freeze-up. If drain line is installed downstream from the
external trap, pitch the line away from the 548F unit at 1 in.
per 10 ft of run. Do not use a pipe size smaller than the unit
connection.
IV. STEP 4 — RIG AND PLACE UNIT
Inspect unit for transportation damage, and file any claim
with transportation agency. Keep unit upright and do not
drop. Spreader bars are not required if top crating is left on
unit, and rollers may be used to move unit across a roof.
Level by using unit frame as a reference. See Table 1 and
Fig. 4 for additional information. Operating weight is shown
in Table 1 and Fig. 4.
Lifting holes are provided in base rails as shown in Fig. 4
and 5. Refer to rigging instructions on unit.
CAUTION:
A. Positioning
Maintain clearance around and above unit to provide proper
airflow and service access. See Fig. 5.
A properly positioned unit will have the following clearances:
1
/4-in. clearance between roof curb and base rails on each
side and front of unit;
rear of unit. (See Fig. 1, section C-C.)
Do not install unit in an indoor location. Do not locate unit
air inlets near exhaust vents or other sources of contaminated air.
Although unit is weatherproof, guard against water from
higher level runoff and overhangs.
After unit is in position, remove polyethylene shipping wrapper and top crating.
NOTE:
Drain plug is shown in factory-installed position.

A. Field Power Supply
All units except 208/230-v units are factory wired for the
voltage shown on the nameplate. If the 208/230-v unit is to
be connecte d to a 208-v p ower sup ply, the tr ansfor mer must
be rewired by dis connecting the black wire fr om the 230-v
1
/4-in. male spade terminal on the transformer and connecting it to the 208-v
transformer.
Refer to unit label diagram for additional information. Pigtails
are provided for field wire connections. Use factory-supplied
1
/4-in. male spade terminal from the
splices or UL (Underwriters’ Laboratories) approved copper/
aluminum connector .
When installing units, provide a disconnect per the NEC. All
field wiring must comply with the NEC and local
requirements.
Install field wiring as follows:
1. Install conduit through side panel ope nings . For units
without electric heat, install conduit between disconnect and control box.
2. Install power lines to terminal connections as shown
in Fig. 6.
3. For units with electric heat, refer to Accessory Electric Heat Installation Instructions.
During operation, voltage to compressor terminals must be
within range in dicate d on unit n amepla te (a lso se e Tables 2A
and 2B). On 3-ph as e uni ts, vo lta ge s be tw e en ph as es mu st be
balanced within 2% and the current within 10%. Use the formula shown in Tables 2A and 2B, Note 2, on page 12 to
determine the percentage of voltage imbalance. Operation on
improper line v oltage or excessive phas e imbalance constitutes abuse and may cause damage to electrical components.
Such operation invalidates any applicable Bryant warranty.
NOTE: If accessory thru-the-bottom connections and roof
curbs are used, refer to the thru-the-bottom accessory installation instructions for information on wiring the unit.

B. Field Control Wiring
Install a Bryant-approved accessory thermostat assembly
according to installation instructions included with the
accessory. Locate thermostat asse mbly on a solid wall in the
conditioned space to sense average temperature in accordance with thermostat installation instructions.
NOTE: If using Bryant electronic thermostat, set thermostat
configuration f or “non-hea t pump opera tion.” The use of the
O terminal is not required to energize the reversing valve in
this family of products.
Route thermostat cable or equivalent single leads of colored
wire from subb ase term inals to low-voltage conne ctions on
unit (shown in Fig. 7) as described in Steps 1 through 3
below.
NOTE: For wire runs up to 50 ft, use no. 18 AWG (American
Wire Gage) insulated wire (35 C minimum). For 50 to 75 ft,
use no. 16 AWG insulated wire (35 C minimum). For over
75 ft, use no. 14 AWG insulated wire (35 C minimum). All
wire larger than no. 18 AWG cannot be dire ctly c onn ected to
the thermostat and will require a junction box and splice at
the thermostat.
